1. An aquarium tank viewing window having at least one fenestration comprisng:
- a water pressure resistive transparent viewing panel having a dry side and an opposing water side;
flange means along the margin of said fenestration protruding inwardly in a common plane operative to confront said water side adjacent the margins of said viewing panel in a substantially flush fitting joint;
bar frame means operative to confront said dry side adjacent the margins of said viewing panels;
means supporting said bar frame against said dry side for maintaning a water-tight seal between said flange means and said water said;
means shrouding said bar frame means and said bar frame supporting means and a second viewing panel mounted in said shrouding means for protecting an area between said water pressure resistive viewing panel and said second viewing panel;
means hinging said shroud means to said fenestration for permitting ready access to said protected area; and
means for locking said shrouding means to said fenestration for preventing unauthorized access to said protected area.

Abstract
A viewing window structure for an aquarium tank and the like includes a removable water pressure resistive viewing panel which presents a substantially uniform water-tight face to the water side thereof. The window structure comprises supporting seat means embedded in a tank wall adapted to receive the water encountering viewing panel. A flange of the supporting seat means is operative to sealably confront the water side of the window panel and to provide a substantially flush water-tight seal. Pressure retaining frame means and supporting hardware are provided on the dry side of the window panel.

2. A viewing window for an aquarium tank having at least one fenestration comprising:
-
a unitary water-pressure resistive transparent viewing panel having a viewing side and an opposing submersible side; said panel being capable of bearing a substantial distributed pressure load on the surface of said submersible side and an equal opposing load along the periphery of said viewing side; a lateral load bearing flange circumscribing the margin of said fenestration having one side confronting the periphery of said submersible side and an opposing side with a substantially uniformly smooth surface; means interposed between said flange means and said submersible side periphery for sealing said fenestration to said viewing panel; adjustable bracing means along said viewing side periphery for supporting said unitary viewing panel; and means for urging said bracing means against said viewing side periphery thereby to maintain said sealing means in water-tight seal along said submersible side periphery. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
